Adding this value to the reported 1448, sums to a total value of 1500 MTU, which is the interface configured MTU. If ESP tunnel mode, the VPN tunnel MTU will be the data payload plus:ДЇor a total size of 52 bytes. The first command displays the MTU value together with the headers and trailers, while the second output displays a MTU value of only the data payload without any headers and trailers. The timings are similar as above only change is that RS is made high for selecting Data register.When running the command show interface tunnel.X, the user sees the interface MTU 1500 show interface tunnel.1Д¬hecking the output of the command show vpn flow tunnel-id X the MTU value is show vpn flow tunnel-id 1Д®ven though there is a different value between the outputs, the firewall shows a correct value in both cases.

step2: Select the Data Register by making RS high.

step4: Send a High-to-Low pulse on Enable PIN with some delay_us.

step3: Select Write operation making RW low.

step2: Select the Control Register by making RS low.

The only important thing is the data should be available on the databus before generating the High-to-Low pulse on EN pin. It is still ok to send the data before these signals. The below image shows the timing diagram for sending the data to the LCD.ДЄs shown in the timing diagram the data is written after sending the RS and RW signals.

In this section, we are going to see how to send the data/cmd to the LCD along with the timing diagrams.ДЇirst let's see the timing diagram for sending the data and the command signals(RS,RW,EN), accordingly, we write the algorithm and finally the code.

You can connect the LCD to any of the PORT pins available on your boards and update this section accordingly

The below configuration is as per the above schematic. This section shows how to configure the GPIO for interfacing the LCD. An HIGH-to-LOW pulse has to be sent on this enable pin which will latch the info into the LCD register and triggers the LCD to act accordingly.Д«elow schematic shows the minimum connection required for interfacing the LCD with the microcontroller.ДЄs we are interfacing the LCD in 4-bit mode, only the higher 4 data lines are used as the data bus. Read/Write(RW): This signal is used to write the data/cmd to LCD and reads the busy flag of LCD.ДЇor write operation the RW should be LOW and for read operation the R/W should be HIGH.Д®nable(EN): This pin is used to send the enable trigger to LCD.ДЄfter sending the data/cmd, Selecting the data/cmd register, Selecting the Write operation. After that the LCD decodes the data for generating the 5x7 pattern and finally displays on the LCD. If the RS signal is HIGH then the LCD interprets the 8-bit info as data and copies it to data register. If the RS signal is LOW then the LCD interprets the 8-bit info as Command and writes it Command register and performs the action as per the command. This signal is used to differentiate the data/cmd received by the LCD. Source IPv6 Address 128-bit field that identifies the IPv6 address of the sending host. NOTE: A G-PDU which includes a PDCP PDU Number contains either the extension header PDCP PDU Number or Long PDCP PDU Number. Bits 8 to 3 of octet 2, and Bits 8 to 1 of octets 5 to 7 shall be set to 0. When it reaches zero, the packet is discarded. Bit 2 of octet 2 is the most significant bit and bit 1 of octet 4 is the least significant bit, see Figure 5.2.2.2A-1. This value is decremented by 1 as it passes through each router. Command can be issued to LCD by writing it to Command register of LCD. IPv6 Packet Header (Cont.) IPv6 packet header fields: Hop Limit 8-bit field replaces the IPv4 TTL field. Any data that needs to be displayed on the LCD has to be written to the data register of LCD. Register Select(RS): The LCD has two register namely a Data register and Command register. It also provides the provision to send the the data/cmd in chunks of 4-bit, which is used when there are limited number of GPIO lines on the microcontroller. Let us look at a pin diagram of a commercially available LCD like JHD162 which uses a HD44780 controller and then describe its operation.ДЄpart from the voltage supply connections the important pins from the programming perspective are the data lines(8-bit Data bus), Register select, Read/Write and Enable pin.Дata Bus: As shown in the above figure and table, an alphanumeric LCD has a 8-bit data bus referenced as D0-D7.ДЄs it is a 8-bit data bus, we can send the data/cmd to LCD in bytes.
